into a Suitable exhaust pipe (not shown). To each side et eaeli setof valve eylinder ports an annular rib B22 ie located.. The ennular rib B22 is formed integral with the valve Cylinder B and tits' into* the correspondingly-"formed grooves and in the valve leed.

C is the covering cap which extends over the valve Cylinder B and is secured by suit able bolts C to the valve 1eed A13 o the engine. The Cap Cie also provided with in terior grooves C2 into which the ribs B22 fit. By this means die gz is prevented from passing between the bed and the valve eyl inder B to the next adjacent set of inlet and exhaust ports.`y ("4 und C5 are spring peeking stripe extending between eaeli of the annular ribs B22 to each side of the exhaust and inlet ports of the valve Cylinder B. These peeking; strips prevent gas 'from passing between the cylinder and valve bed from the inlet to the exhaust port.

Frein this description it will be Seen tliet l nave devised a very simple t'orin of valve which Will be noiseless in its operation,

Wliieli will be positive in action and not liable to get out of order, and in which the ports may be readily packed so as to be isolated one frointlie other.

What I elaiin as my intention is.

l. .ln a device of the class described, the Combination with the cylindrical valve bed having ports leading therefrom, of a eylin l drical Valve journeled therein and conpris i ing an outer Cylindrical member having closed heads, an inner cylindrical member noemer extending longitudinally through tl'ie outer eylindreel member end extending one end through one of the closed heads o die outer cylinder, ports leading` from the outer cylinder and arranged in circumferential alinernent with the ports ot the 'valve bed, porte leading troni the inner Cylindrical ineinber through the outer cylindrical mein ber and also arranged in circumferential elinenient with the ports oi? the valve leed, annular 'files extending from the outer o vlindrieal member et the valve between eaeli set et inlet and exhaust ports into correspendingl grooves in the valve bed. end ea-p and backing strips extending between each pair et annular ribs to each side of eaeli port, as and for the purpose specified.

2. ln en engine, the combination with e plurality of eylinders, a Cylindrical valve bed and perte connecting the interior et the leed and the cylinders together, a rotary valve journaled in the bed, seid valve coniprising an outer and inner Cylindrical inernber, a series of porte in the outer membern a series of porte in the inner inernoera and means :tor preventing the gas leaking 'from one oi the ports to the other, said Ineens Comprising an ennuiar rib between eaeli. or"

the ports, Said annular ribs extending into annular grooves in the interior oi the veive bed.
